Netty 4.1.62.Final released

Just after releasing netty 4.1.61.Final yesterday we decided to do a quick followup release a.k.a netty 4.1.612.Final. to fix a regression that slipped in. The regression affects only users that use the native KQueue transport. For more details please see (#11128). Special thanks to @violetagg for reporting the regression in such a fast manner and also providing a fix for it!
